IMPROVEMENT IN APPARATUS FOR LOADING AND UNLOADING COAL, &c.

Specification forming part of Letters Patent No. 1 51,868, dated June 9,1874; application filed January 29, 1874.

the apparatus for moving and discharging cargoes of coal, grain, ore,850., for which Letters Patent were granted to me on the 6th day ofJanuary, 1874, the object of my present improvement being to guide andprevent the swaying of the bucket in its ascent and descent.

I attain this object by providing the hoisting-rope with a hook, havingan eye, a, at the back, which slides upon a guy-rope, F, secured at itsupper end to a projection, 12, of the jib, which projects outward beyondthe front of the chute, the lower end of the said guy-rope being held byan attendant, who thus guides and prevents the swaying of the bucket,all as shown in the perspective view of the accompanying drawing.

The apparatus is, in the present instance, built at the edge of a wharf;and consists of a light open-work structure, H, having at the front aninclined chute, J partially surround ing which is a platform, d, for theattendants, and the hoisting rope B passes over two sheaves, e and f, atthe top of the apparatus,

and extends through a block, K, suspended from the jib A, and providedwith a rope, L, or equivalent connection, by means of which it may bedrawn inward, as in my aforesaid patent, in order to facilitate thedischarge of the contents of the bucket into the chute.

I have found in practice that when the apparatus is of considerableheight, necessitating the use of a long hoisting-rope, the bucket is aptto sway when rapidly elevated, so that it will frequently strike thefront of the chute and drop a portion of its contents.

To prevent this, I construct the hook at the end of the hoistin g-ropefrom which the bucket is suspended with an eye, a, at the back, andthrough this eye I pass a guy-rope, E, which is held by an attendant whostands on the deck of the boat adjacent to the hatchway, and is thusenabled to guide and prevent all risk of the striking of the bucketagainst the chute.

The guy'rope F is suspended from a projection, I), of the jib, whichextends outward considerably beyond the sheave e of the hoisting-rope,and beyond the front of the chute, so that it is not absolutelynecessary to draw the guy-rope outward, as shown; for, if merely held ina vertical position, the said rope will so guide the bucket as to causeit to clear the chute, and may then be released, in order to permit thesaid bucket to be drawn inward.

I claim as my invention- 1. The hook on the hoisting-rope, constructedsubstantially as described, with an eye, a, at

the back, for the purpose specified.

2. The combination of the hook on the hoisting-rope, its eye a, theguy-rope F, and the projection b of the jib, extending outward beyondthe sheave e of the hoisting-rope and beyond the front of the chute, allsubstantially' as and for the purpose specified.

In testimony whereof I have signed myname to this specification in thepresence of two subscribing witnesses.
